In response to some feedback, I'd like to explain clearly; the point of this answer is not to suggest that a dog drinking his own urine is by any means optimal, either for his health, or as a behavior, I am merely stating that if the animal is not let out to go to the toilet often enough and then does the best he can to correct his mishap; he should not be scolded for this. The idea behind this, is treating the cause of the behavior, rather than treating the symptoms.
I am not disagreeing with @John's answer in principle; just providing an alternate answer based on the reason your dog is relieving himself in the house; as per your linked question Why is my dog drinking his pee after he urinates inside?.
Behaviour like this is normal, if the dog is not doing it outside, but only within the house. My answer here Why is my dog drinking his pee after he urinates inside? explains this in more detail.
Given the dog is going with his natural instincts and trying to keep the den (your home) clean, I wouldn't go with any sort of negative feedback, as it's confusing to the dog.
The key to breaking this habit is to ensure
you dog doesn't have any health problems preventing him from holding on
to take your dog out for more frequent toilet breaks
to provide, if possible, a dog door, so he can access the outdoors and relieve himself as needed.
Although it is unpalatable to watch, urine (in it's healthy state) is sterile and no harm will actually come to your dog from doing this from time to time.
After a bit of thought it also occurred to me; if you catch him in the act of doing this, it might be an idea to call him
Rover! high pitched voice, in the tone of
quick come and see this! and run to the back door with him and take him outside. It's not a direct reward for the behavior, but like an acknowledgment of
yes, that's yuck, let's go outside and also serves as a complete distraction.
Ingesting its own urine is very unlikely to cause any significant problems in a dog, since any organisms in the urine are already present in the dog's system. As long as another water source is freely available there should be no problem.
